43.—(1) Concession contracts may be modified without a new concession contract award procedure in accordance with these Regulations in any of the following cases—
(a)where the modifications, irrespective of their monetary value, have been provided for in the initial concession documents in clear, precise and unequivocal review clauses, which may include value revision clauses or options, provided that such clauses—
(i)state the scope and nature of possible modifications or options as well as the conditions under which they may be used, and
(ii)do not provide for modifications or options that would alter the overall nature of the concession contract;
(b)for additional works or services by the original concessionaire that have become necessary and were not included in the initial concession contract where a change of concessionaire—
(i)cannot be made for economic or technical reasons such as requirements of interchangeability or interoperability with existing equipment, services or installations procured under the initial concession contract, and
(ii)would cause significant inconvenience or substantial duplication of costs for the contracting authority or utility,
provided, in the case of a concession contract awarded by a contracting authority, that any increase in value does not exceed 50% of the value of the original concession contract;
(c)where all of the following conditions are fulfilled—
(i)the need for modification has been brought about by circumstances which a diligent contracting authority or utility could not have foreseen,
(ii)the modification does not alter the overall nature of the concession contract,
(iii)in the case of a concession contract awarded by a contracting authority, any increase in value does not exceed 50% of the value of the original concession contract;
(d)where a new concessionaire replaces the one to which the contracting authority or utility had initially awarded the concession contract as a consequence of—
(i)an unequivocal review clause or option in conformity with sub-paragraph (a),
(ii)universal or partial succession into the position of the initial concessionaire, following corporate restructuring, including takeover, merger, acquisition or insolvency, of another economic operator that fulfils the criteria for qualitative selection initially established, provided that this does not entail other substantial modifications to the contract and is not aimed at circumventing the application of these Regulations;
(e)where the modifications, irrespective of their value, are not substantial within the meaning of paragraph (9);
(f)where paragraph (5) applies.
(2) Where several successive modifications are made—
(a)the limitations imposed by the proviso at the end of paragraph (1)(b) and by sub-paragraph (c)(iii) shall apply to the value of each modification; and
(b)such successive modifications shall not be aimed at circumventing these Regulations.
(3) Contracting authorities and utilities which have modified a concession contract in either of the cases described in paragraph (1)(b) and (c) shall send a notice to that effect for publication in accordance with regulation 33.
(4) Such a notice shall contain the information set out in Annex XI to the Concessions Directive.
(5) This paragraph applies where the value of the modification is below both of the following values—
(a)the threshold mentioned in regulation 9, and
(b)10% of the value of the initial concession contract,
provided that the modification does not alter the overall nature of the concession contract.
(6) For the purposes of paragraph (5), where several successive modifications are made, the value shall be the net cumulative value of the successive modifications.
(7) For the purpose of the calculation of the values mentioned in paragraphs (1)(b) and (c) and (5)(b), the updated value shall be the reference value when the concession contract includes an indexation clause but if the concession contract does not include an indexation clause, the updated value shall be calculated taking into account the average inflation in the United Kingdom.
(8) For the purposes of paragraph (7), average inflation shall be determined by reference to any one or more of the following indices published by the Statistics Board M1 or, if any such index ceases to be published, such other index as may replace it—
(a)the Retail Prices Index, being the general index of retail prices (for all items);
(b)the Consumer Prices Index, being the general index of consumer prices (for all items);
(c)the Producer Prices Index, being the index of price changes of goods bought and sold by United Kingdom manufacturers;
(d)the Services Producer Price Index, being the index of changes in the price received for selected services provided by United Kingdom businesses to other United Kingdom businesses and government.
(9) A modification of a concession contract during its term shall be considered substantial for the purposes of paragraph (1)(e), where one or more of the following conditions is met—
(a)the modification renders the concession contract materially different in character from the one initially concluded;
(b)the modification introduces conditions which, had they been part of the initial concession contract award procedure, would have—
(i)allowed for the admission of other applicants than those originally selected,
(ii)allowed for the acceptance of a tender other than that originally accepted, or
(iii)attracted additional participants in the concession contract award procedure;
(c)the modification changes the economic balance of the concession contract in favour of the concessionaire in a manner which was not provided for in the initial concession contract;

(e)a new concessionaire replaces the one to which the contracting authority or utility had initially awarded the concession contract in cases other than those provided for in paragraph (1)(d).
